如何阻止無限循環？

Question

我正在製作腳本遊戲並使用此代碼進行多項選擇。

while True: 
d1a = input ("Do you want to: A) Befriend Fred. B) Be mean to Fred. [A/B]? : ") 
if d1a == "A": 
    print ("You befriend fred. You now have a friend..") 
elif d1a == "B": 
    print ("You angered Fred. He kills you. RIP.") 
elif d1a == "Q" : 
    break 

在此之後發生的，如果A型或B將打印所需的文本，然後再次問你「你要交好弗雷德？」如果你想要一個迭代循環是沒有必要離開後循環

while True: 
    d1a = input ("Do you want to: A) Befriend Fred. B) Be mean to Fred. [A/B]? : ") 
    if d1a == "A": 
     print ("You befriend fred. You now have a friend..") 
     break 
    elif d1a == "B": 
     print ("You angered Fred. He kills you. RIP.") 
     break 
    elif d1a == "Q" : 
     break

您可以簡單地添加break語句每個條件。然而，我假設你循環，直到你得到正確的輸入，在這種情況下，它可能是不錯的告訴您的播放器，輸入是不正確的：

while True: 
    d1a = input ("Do you want to: A) Befriend Fred. B) Be mean to Fred. [A/B]? : ") 
    if d1a == "A": 
     print ("You befriend fred. You now have a friend..") 
     break 
    elif d1a == "B": 
     print ("You angered Fred. He kills you. RIP.") 
     break 
    else: 
     print("Incorrect input")
